LONGi · solar panel for commercial rooftops
LONGi Hi-MO X10 Scientist solar panel, 640–670 W
LONGi's top rooftop panel: a single-glass module on HPBC 2.0 cells with efficiency up to 24.8% at a weight of just 28.5 kg. No gridlines on the front face, so the panel copes with partial shading noticeably better than a conventional TOPCon module.
Five kilograms lighter
28.5 kg against 33.5 kg for dual-glass modules of the same rating. On a roof with light trusses that is the deciding argument.
Tolerates shade
Back-contact cells have no front gridline, and the soft-breakdown design cuts losses when a flue, aerial or tree shades part of the array.
24.8% efficiency
The most LONGi builds for distributed generation. The same roof yields noticeably more kilowatts.
15 and 30 years of warranty
15 years on the product and 30 years on linear power output: at least 88.85% remaining at year 30.
Shipped from stock in Krasnodar across Russia. Send us the array size and grid phase configuration — our engineer will check the inverter selection and string layout before dispatch.
